Java source code for firewall

Hi everybody

I am planning to create a packet filter firewall in my project using java. Is there anybody who knows where I can get free java open source code for a firewall? I have searched for two days online trying to get a free java source code, but all the codes are made in C or C++. I have never learned C or C++.

Thanks ahead.

if you are looking at someone elese source-code are you actually creating it? seems like you are stealing it.

do your own research into how a firewall would work in java (there are many different types these days) and implemented yourself, using the java features you know (or learn during research).

Why do you have to post the same question 3 times?

hi there. There are no API of java own to create a firewall application.One needs to write the firewall code in c++ using windows firewall API and then can use native code to link it with Java if needed......:-)

Firewalls cannot be implemented in Java. If you want C or C++ you are asking in the wrong place.

To make operating system to drop or accept packets you have to have access to system network API.

In windows you have to pay alot of money to do that.

In GNU/Linux OS this is more easy thing. You could use netfilter libraries or just looking in libraries code for kernel api. These libraries are written in C. To use these libraries in java you have to write java native code.
